This hasn't happened to me in years, back when money was tighter and priorities were different (beer first, then gas). However I was pushing it earlier this year as I was coming back from Lexington, Kentucky. I misjudged how far I had to go to Nashville, and by the time I got there that night I was frighteningly close to E. I was having trouble getting right to take an exit, but finally managed to do so. Just as I was pulling up to the pumps the idiot light came on telling me I was low on fuel. That's as close as I care to come to running out of gas on the freeway in Nashville. Or anywhere else for that matter.
